The central successes and
puzzles of particle physics will be reviewed, the discovery of
the Higgs boson at the CERN Large Hadron Collider (LHC)
illustrating both aspects. The grand principle of Naturalness
will be introduced as the dominant organizing principle behind
many searches for new physics beyond the Standard Model. The
challenging task of testing naturalness will be summarized,
especially the interplay between deep theoretical ideas, such as
Supersymmetry, Compositeness, Extra Dimensions and Hidden
Naturalness, and experimental strategies at the LHC and even
more powerful future colliders. The LHC is beginning its second
phase of operations, at significantly higher energies than
before, and this talk will give a satellite view of the big
issues at stake in the coming years.

About the Speaker:

Raman Sundrum is a Distinguished University Professor at the
University of Maryland, working in theoretical particle physics,
and he is the Director of the Maryland Center for Fundamental
Physics. He obtained his PhD from Yale University in 1990, after
which he did postdoctoral fellowships at UC Berkeley, Harvard,
Boston University and Stanford, before joining the physics
faculty at Johns Hopkins in 2000. He moved to his current
position at Maryland in 2010. He is best known for co-authoring
the "Randall-Sundrum" scenario for particle physics based on
"warped" higher-dimensional spacetime. It has led to many
developments in particle theory, string theory, and gravity
theory, and it has inspired a number of experimental searches at
the CERN Large Hadron Collider. Dr. Sundrum also works on
Supersymmetry, cosmology, and quantum field theory.
